We consider the possibility of generation primordial magnetic field on inflation and show that effect back reaction this can be very important. Assuming does not spoil we find a rather strong restriction amplitude which could generated inflation. Namely, recalculated to present epoch cannot exceed 10−32G in Mpc scales. This seems too small amplified observable values by possible dynamo mechanism.
Our main goal was to investigate if robust chemical fingerprints could be developed for three Argentinean red wines based on organic, inorganic, and isotopic patterns, in relation the regional soil composition. Soils from regions (Mendoza, San Juan, Córdoba) varieties (Cabernet Sauvignon, Malbec, Syrah) were collected. The phenolic profile determined by HPLC-MS/MS multielemental composition ICP-MS; (87)Sr/(86)Sr δ(13)C TIMS IRMS, respectively. Chemometrics allowed differentiation between...
A general review of the electromagnetic properties hadrons when interpreted as composite states quarks is given. Electromagnetic mass formulas are derived using two-body forces. The one-particle contributions to magnetic moments baryons and decays vector mesons calculated without any assumptions about $U$-spin transformation photon. spin-$\frac{3}{2}$ in a way analogous Becchi-Morpurgo calculation rate for...
We put bounds on the variation of value fine structure constant $\ensuremath{\alpha}$, at time big bang nucleosynthesis. study carefully all light elements up to ${}^{7}$Li. correct a previous upper limit $|\ensuremath{\Delta}\ensuremath{\alpha}/\ensuremath{\alpha}|$ estimated from ${}^{4}\mathrm{He}$ primordial abundance and we find interesting new potential limits (depending baryon-to-photon ratio) ${}^{7}\mathrm{Li},$ whose production is governed large extent by Coulomb barriers. The...
We study the generalized superconvergent sum rules for a number of processes kind $P+P\ensuremath{\rightarrow}P+V$, where $P$ and $V$ stand pseudoscalar vector mesons, respectively. find simple algebraic equations parameters leading Regge trajectories which are exchanged. The results in good agreement with experiments. limit SU(3) symmetry is also considered.
In this paper we study the reactions $\ensuremath{\pi}\ensuremath{\pi}\ensuremath{\rightarrow}\ensuremath{\pi}\ensuremath{\omega}({1}^{\ensuremath{-}})$, $\ensuremath{\pi}\ensuremath{\pi}\ensuremath{\rightarrow}\ensuremath{\pi}{A}_{2}({2}^{+})$, and $\ensuremath{\pi}\ensuremath{\pi}\ensuremath{\rightarrow}\ensuremath{\pi}{\ensuremath{\omega}}_{3}({3}^{\ensuremath{-}})$ as a bootstrap system for natural-parity trajectories. We start from solution of our previous work that gave, among other...
The optical properties of the ice at geographical South Pole have been investigated depths between 0.8 and 1 kilometer. absorption scattering lengths visible light ( approximately 515 nanometers) measured in situ with use laser calibration setup Antarctic Muon Neutrino Detector Array (AMANDA) neutrino detector. is intrinsically extremely transparent. length 59 +/- 3 meters, comparable quality ultrapure water used Irvine-Michigan-Brookhaven Kamiokande proton-decay experiments more than twice...
We study the asymptotic properties of virtual Compton scattering amplitude for a spacelike spin-1 photon off scalar target, in limit ${k}^{2}\ensuremath{\rightarrow}\ensuremath{\infty}$, $\frac{\ensuremath{\nu}}{{k}^{2}}=\ensuremath{\rho}$ fixed. This is accomplished by means perturbative model based on ladder-diagram series. The absorptive parts these amplitudes forward direction are related, as well known, to structure functions ${W}_{1}$ and ${W}_{2}$ that turn describe inelastic electron...
